Bill,

AMC2 receiver stopped tracking after 1998/12/2 00:09:30. It re-started
tracking at 1998/12/02 23:47:00 and collected PRN 19 data; then stopped
tracking again.

This morning we rebooted the receiver by using the 'bang' command which
reloaded the receiver firmware from the flash EPROM onto the RAM memory.
The receiver restarted tracking after a few minutes. 

Miranda

Miranda,

Thanks for the information.  In the future, when you see it has stopped 
tracking please let me know.  If I can, I will try and determine the cause.  I 
will also try to restart the tracking locally.

To my knowledge, there were no operations conducted at the AMC which would 
have caused the receiver to stop tracking.  Do you know the possible reasons 
this would occur and is there anything I can check locally?

Bill
